Data exploring the effects of food availability on growth of sea bass reared under environmental stressors of ocean acidification and warming CominassiLouise MoyanoMarta ClaireauxGuy HowaldSarah MarkFelix Christopher Zambonino-InfanteJosé-Luis PeckMyron A 2020 <div>This dataset contains four Excel <b>.xlsx </b>spreadsheets of measurements relating to the combined effects of food availability, ocean acidification and ocean warming (OAW) on fish growth.</div><div><br></div><div>Fish (sea bass, <i>Dicentrarchus labrax</i>) were reared in four treatment groups, defined by water temparatures of 15°C or 20°C and concentration of carbon dioxide (<i>P</i>CO2) of 650 µatm (ambient acidification) or 1750 µatm (high acidification), all under <i>ad libitum</i> feeding. Following this, feeding trials were performed with <i>ad libitum </i>and 25% of <i>ad libitum </i>rations at ambient and elevated (+1100 µatm) levels of <i>P</i>CO2.</div><div><br></div><div>Details of the four spreadsheets are as follows:<br></div><div>- <b>Data_Daily Food.xlsx</b>: Mass (g) of food distributed per tank per day during the feeding trial. Abbreviations: AL, <i>ad libitum</i>; 25AL, 25% <i>ad libitum</i>; Tot_fish, Total number of the fish in the tank.</div><div>- <b>Data_Enzymes.xlsx</b>: Values of total and specific activities of trypsin, phosphatase alkaline (PA), amylase and aminopeptidase N (LAP) measured on randomly selected fish. Abbreviations: AL, <i>ad libitum</i>; 25AL, 25% <i>ad libitum</i>; bb, Brush border; scrap, Scrapping.<br></div><div>- <b>Data_Mass.xlsx</b>: Individual mass of the fish at the beginning and the end of the feeding trial. Abbreviations: AL, <i>ad libitum</i>; 25AL, 25% <i>ad libitum</i>; Fish_nber, Fish number; Mass_1, Initial mass; Mass_2, Final Mass.<br></div><div>- <b>Data_Stomach pH.xlsx</b>: pH values of the stomach of randomly selected fish, measured post feeding, using a pH sensor. Abbreviations: AL, <i>ad libitum</i>; 25AL, 25% <i>ad libitum</i>; Fish_nber, Fish number.<br></div><div><br></div><div>The related publication aimed to determine whether the provision of <i>ad libitum </i>rations may provide ample energy to organisms in multiple stressor environments, thereby allowing them to compensate for potential negative impact of sub-optimal levels due to the stressors (in this case, temperature and/or <i>P</i>CO2) on energy acquisition, dissipation and allocation.</div>
